Specify the type of the MAC addresses mapped to the virtual IP addresses before creating a VRRP group.

You cannot change the address mapping setting after a VRRP group is created.

To specify the type of MAC addresses mapped to virtual IP addresses:

Specifying the VRRP control VLAN

With VLAN termination, after a port receiving a VLAN packet, it removes its VLAN tags and then

forwards it at Layer 3 or processes it in other ways. VLAN termination includes the following categories:

• Unambiguous termination—Terminates VLAN packets from a specified VLAN only. In other words,

after receiving a packet from the specific VLAN, a port configured with unambiguous VLAN

termination removes its VLAN tag.

• Ambiguous termination—Terminates VLAN packets from multiple VLANs whose VLAN IDs are in

the specified range. In other words, after receiving a packet from a VLAN in the specified range, a

port configured with ambiguous VLAN termination removes its VLAN tag.

By default, an ambiguous termination-enabled Layer 3 subinterface or VLAN interface drops broadcast

and multicast packets they receive, instead of transmitting them.

You can enable a Layer 3 Ethernet subinterface, or a VLAN interface configured with ambiguous

termination to transmit broadcast/multicast packets within all VLANs whose VLAN packets are

configured to be terminated by the subinterface or VLAN interface.

Figure 43 VRRP control VLAN

As shown in Figure 43, configure ambiguous VLAN termination for VLAN 10 and VLAN 20 on the Layer

3 Ethernet subinterfaces on routers. To enable the master periodically multicasting VRRP advertisements

to the backups, be sure to enable the subinterfaces configured with VLAN termination to transmit

broadcast/multicast packets. Then, the master sends VRRP advertisements within all VLANs whose VLAN

packets are configured to be terminated by the subinterfaces. If the Layer 3 Ethernet subinterfaces are
